SPECIFICATION forming part of Letters Patent No. 292,207, dated January 22, 1884.

- Application filednprneisss. (No model.)

To ZZZ whom t may concern:

Be it known that I, PHILIP F. OoRBnrr, of

i. Boston, in the county of Suffolk, State -of Massachusetts, yhave invented a certain new and useful Improvement in Vises, of which the following is a description suiciently full,

clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, A

forming a part of this/specilicationpin which- Figure 1 is an isometrical perspective View; Fig. 2, a vertical transverse section taken on line x; Fig. 3, a like view taken on line z,- Fig. 4, a longitudinal sectional view of the head-stock, and Fig. 5 a vertical longitudinal section. o

Like letters of reference indicate corresponding parts in the different iigures of the drawings. My invention relates to that class ofvise which are employed for bench use by carpenters, 'cabinet-makers, and other wood-workers; and it consists ina novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a simpler, cheaper, and more effective device of this character is produced than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all con-, versant with such matters from the following explanation, its extreme simplicity rendering an elaborate description unnecessary.

In the drawings, A represents the body of the vise, B the head-stock, and G the tail-stock.

The body 'is provided on either side with a longitudinal groove, m, running its entire length, and on its top with an iron cap-plate,

D, which is secured to the body by the screws w.

The headstockconsists of two downwardlyof movement are gained over a single engagevment.

The tail-stock consists of two downwardlyprojecting flanges or side pieces, M, connected by the cross-bar or upright N above the body A, the side pieces being vprovided at their outer ends with inwardly-projecting studs f, which work in the grooves m.

The plate D is provided with a series of vertical holes, g, and projecting downwardly from the bar N there is a stud or pin, Z, adapted to enter the holes and secure the tail-stock in any desired position on the body A. A like the bar G of the head-stock and serves a like purpose. 'o

In Fig. 5 a modification of my improvement is shownvwhich is preferable for heavy work.

Projecting downwardly and backwardly from either end of the bar G, and next the side pieces, E, there is a tooth or dog, P, adapted to enter a corresponding mortise or slot, h, cut in the side of the `body A, the slot inclining toward the tail-stock end of the vise, as shown. A like tooth or dog, fi, projects downwardly from either end of the bar, C, next theside pieces, M, adapted to engage in the series of mortises or slots Q, also formed in the side of the body A, but inclined toward the head-stock end of the vise, or in an opposite direction to the mortise h.

In the use of my improvement the body A is placed on any convenient bench or support, and its head-stock adjusted as shown, the pin in the lower part of the bar G being in one of the holes g and the studs d in .the grooves m.

onis thenplaced across the top of the body or bed A, between the head and tail stocks, and the tail-stock movednup as closely as possible to the article to be clamped, the studs f being in the grooves m. The pin or stud Z is then pushed downwardly into one of the holes grand the screw J turned in by the handle L, causing the work to be grasped between the will be readily obvious without a more explicit description.- The guard K is tted loosely on the screw J, so that the screw may be turned without turningv the guard and injuring the work. The tooth P, being inclined as, shown, and hooking into the inclined mortise or slot pin (not shown) projects downwardly from The work to be glued or otherwise operated guard K and tail-stock C in a manner which ICO 71, prevents the inner end of the head-stoek frein rising when a great strain is pnt on the screw J in doing heavy work. The tooth 'i also, in like nianner, by hooking into the 111ertises Q, keeps the tail-stock in proper position.

1t will be obvious that the inner ends of the head and tail stocks may be raised to enable the Work to be inserted in the vise to better advantage, the stocks being respectively pivoted on the studs df.

The sides E and bars G H of the head-stock are cast integral or in one piece. rIhe sides )I and bar N of the tail-stock are also cast integral, and the body may be lnade of east metal, or of wood and metal, as preferred.

It will be obvious that both the head and tail stocks may be readily removed from the body A, thereby adapting one set of stocks for use with several bodies, or, in other Words, preventing the necessity of having a body or bed-piece for each set of stocks.

Having thus explained my invention, what I claiin isl. In a clamping-vise, ahead-stock coniposed of downwardly-projeeting cheeks or side pieces provided with inwardly-projecting l studs that slide in side grooves of the body,

the nprights G and H, connecting the side pieces, a pin or dog adapted to enter a series of holes in thetop plate ofthe body, and ahorizontal screw extending through and engaging both uprights, in combination With the body provided with a longitudinal groove on each side, and with a tail-stock, substantially as described.

2. In a clamping-vise, a tail-stock coniposed of downwardly-projeeting cheeks or side pieces provided with inuardly-projecting studs that slide in side grooves of the body, the crossbar N, between the cheeks, and a pin adapted to enter a series of holes in the top plate of the body, in combination lwith the body provided with a longitudinal groove on each side, and a head-stock provided with nprights G and H, and a screw which engages both of said uprights, substantially as described.
